Compared to your weight and mass on Earth, if you were on the moon:
your weight and mass would be less.
your weight would be less but your mass would remain the same.
your weight would remain the same, but your mass would be less.
your weight would be greater, but your mass would remain the same.
What is the weight of your backpack in Newtons? The mass of your backpack is 10 kg. (assume: g = 9.8 m/s2)
10 N
9.8 N
98 N
980 N
The correct equation to solve for weight in Newtons is:
W = m/g
W = g/m
W = grams
W = mg

0.306 N
3 N
29.4 N
58.8 N
